Chambal

According to folklore the Chambal area was part of Shakuni’s kingdom and the dice-game played thereabouts. After the attempted disrobing of Draupadi (the daughter of Drupada) she cursed any one who would drink the water of the Charmanwati river. Thus it is believed that due to the curse by Draupadi, have helped the Chambal to survive unpolluted by man, and its many animal inhabitants to thrive relatively untouched. The Chambal remains one of India’s most pristine rivers.
